Then you are proposing these people are more powerful than the Holy Spirit. Which is really pretty blasphemous.
More scary than blasphemous. It is like these people forcing some spiritual infection decease into your soul, then after that you turn around and ask the Holy Spirit what can be done. You are lucky if you even know how to properly identify the nature of your problem with these in your confession and repentance. The Holy Spirit is here the doctor banging his head on the wall in a desperate effort of saving the dying idiot who was thrown into the infection.
An even better explanation is the Good Samaritan story. When somebody has forced the devil into you, you are like that traveler after he got mugged on his way to Jerico. The Holy Spirit is the Samaritan who takes you to the inn which is the Church, and puts oil on you to slow down your death. The 2 coins is Jesus's 2 central commandments, which your church gets to take care of you. Did the traveler survive in that parable? I think it doesn't say. If not, then was the devil stronger than the Holly Spirit with his oil and inn and all?
